This study aims to explore how in-service science teachers adopt newly developed 'Science' focusing on the fusion of science based on 'the diffusion of innovation' model. For this study, we have explored five variables (i.e., perception of need, perception of support, innovativeness, perceived usefulness, self-efficacy of teaching, and intention to adopt) based on literature review and developed survey items to measure the level of five variables that in-service science teachers perceive. In addition, the path model of six variables explaining how in-service science teachers adopt an innovation was hypothesized by the literature review. A total of 349 in-service science teachers have participated in this survey study. First of all, results have illustrated that the levels of six variables have not significantly associated with in-service science teachers' teaching experiences, participation in professional development programs on 'Science' curriculum, and majors. In addition, the statistically acceptable model fit indices have illustrated that path model has been statistically valid to explain how in-service science teachers adopt newly developed 'Science' focusing on the fusion of science. The results have also illustrated that 'perception of support', 'perceived usefulness', and 'self-efficacy of teaching' exhibited strong mediating effects between other variables. For the successful establishment of newly developed curricula, textbook, or policies in science education in school, the level of teachers' intention to adopt innovations should be enhanced. This study will be useful for the development of new science teacher professional development programs to promote the level of teachers' intention to adopt innovations.

The main goal of this study is to investigate the importance of trust as a mediator between shopping experience and shopping value. Previous studies on utilitarian shopping value and hedonic shopping value have focused on the antecedents and outcomes of those shopping values. Also, although the role of trust has been studied a lot in the series of studies on online shopping mall, most of them focus on the relationship with intention to shop or use and there are few studies on the mechanism in which consumers get to have shopping value. This study tries to see how trust can boost utilitarian shopping value and hedonic shopping value which can lead to consumer's loyalty to the shopping mall. A structural equation model is proposed and examined through a survey research to investigate the role of trust in forming perceived shopping value. One model included the trust variable as a mediator and the other excluded it. The comparison of R2 verified that the first model had a better fit. The results of the study show that the level of experience has a significant impact on both utilitarian and hedonic shopping values in the case of the model without the mediator. But experience has an insignificant or a partially significant effect on utilitarian and hedonic shopping values when trust mediates experience and shopping values. Finally, the implications and limitations are further discussed.

Developed countries have developed indicators of quality of life and are using them as indicators of policy decisions, and Korea is also developing and operating indicators of people's quality of life. One of them is a lifestyle-oriented SOC, a policy that aims to improve the quality of life of the people by improving living infrastructure. This study aims to focus on subjective happiness among people's quality of life. The elderly are a relatively marginalized class in the national policy, and this study aims to analyze the effects of the elderly's residential environment on quality of life, housing satisfaction, and happiness. The purpose of this study is to provide useful implications for urban planning and related policy making by examining the structural relationship of whether the individual-environmental fit perceived by the elderly affects housing satisfaction and subjective happiness, and by analyzing the mediating effect between housing satisfaction and subjective happiness. As a result of the study, it was found that convenience, comfort, and public welfare of personal-environment suitability affect housing satisfaction and subjective happiness, and housing satisfaction affects subjective happiness. Also, it was analyzed that housing satisfaction had a mediating effect in the relationship between comfort, public welfare, and subjective feeling of happiness.

The understanding and capability to utilize artificial intelligence (AI) incorporated technology has become a required basic skillset for the people living in today's information age, and various members of the university have also increasingly become aware of the need for AI education. Amidst such shifting societal demands, both domestic and international university libraries have recognized the users' need for educational content centered on AI, but a user-centered service that aims to provide personalized recommendations of digital AI educational content is yet to become available. It is critical while the demand for AI education amongst university students is progressively growing that university libraries acquire a clear understanding of user intention towards an AI educational content recommender system and the potential factors contributing to its success. This study intended to ascertain the factors affecting acceptance of such system, using the Extended Technology Acceptance Model with added variables - innovativeness, self-efficacy, social influence, system quality and task-technology fit - in addition to perceived usefulness, perceived ease of use, and intention to use. Quantitative research was conducted via online research surveys for university students, and quantitative research was conducted through written interviews of university librarians. Results show that all groups, regardless of gender, year, or major, have the intention to use the AI-related Educational Content Recommendation System, with the task suitability factor being the most dominant variant to affect use intention. University librarians have also expressed agreement about the necessity of the recommendation system, and presented budget and content quality issues as realistic restrictions of the aforementioned system.

This study aimed to propose an appropriate evaluation method for the perceived level of speech disfluency based on sound prolongation (i.e., increased duration of segments). To this end, 34 Korean-speaking adults (9 males, 25 females, average age: 32.9 yrs.) participated as raters in this study. The participants listened to sentences containing a total of 25 stimuli with the Korean voiceless fricative /s/ extended by 80-ms increments up to 2,000 ms (i.e., 285 ms, 365 ms., ..., 2,125 ms, 2,205 ms), and evaluated them using an equal-appearing interval scale (EAI, 1-7 points, where 1 represents "normal" and 7 represents "severe"). Subsequently, based on the interval-scale results, the sentence stimuli with the prolonged voiceless fricative corresponding to the mild-to-moderate level (rated as 4 points) were selected as the reference modulus for direct magnitude estimation (DME). After scatter plots were created for the two evaluation results, the relationship between the two measured mean values was analyzed using a curve estimation method for the observed data with the highest R²-value to determine whether a linear or curvilinear approximation fit the data better. A curvilinear relationship between the two evaluation results was indicated, suggesting that DME is a more appropriate evaluation method than the EAI scale for assessing the perceived level of disfluency based on sound prolongation.

The purpose of this study is to suggest a new concept of the absolute sound level system in order to basically solve all the irrational aspects from the mastering stage to the output stage during the process of producing a sound source. Through this absolute sound level system, all the input absolute sound levels of sound sources become standardized based on 60 dB(S), and then sound source producers can implement a sound level they intend by using the differential sound level tag. Besides, by matching the output absolute sound level with the input absolute sound level, a target sound level can be implemented as a listener intends. With this system introduced, sound source producers are able to focus on the completion of a sound source itself without an unnecessary competition for sound levels, and only by inputting the differential reduction tag, they can implement a sound level balance as intended. At the same time, listeners are able to appreciate all kinds of sound sources fit for the standard of absolute s ound levels they want to listen to, without a process of trial and error, no matter what kinds of listening environments and sound systems they have.

This study was designed to construct a structural model for quality of life of chronic gastric disease. The hypothetical model was developed based on the literature review and Pender's health promotion model. Data were collected by questionnaires from 459 patients with chronic gastric disease in a General Hospital from July 1999 to August 2000 in Seoul. Data analysis was done with SAS 6.12 for descriptive statistics and PC-LISREL 8.13 Program for Covariance structural analysis. The results are as follows : 1. The fit of the hypothetical model to the data was moderate, thus it was modified by excluding 1 path and including free parameters and 2 path to it. The modified model with path showed a good fitness to the empirical data ($\chi$2=934.87, p<.0001, GFI=0.88, AGFI=0.83, NNFI=0.86, RMSR =0.02, RMSEA=0.07). 2. The perceived barrier, health promoting behavior, self-efficacy, and self-esteem were found to have significant direct effects on the quality of life. 3. The health concept, health perception, emotional state, and social support were found to have indirect effects on quality of life of chronic gastric disease. In conclusion, the derived model in this study is considered appropriate in explaining and predicting quality of life of chronic gastric disease. Therefore it can effectively be used as a reference model for further studies and suggested direction in nursing practice.

Purpose: The purpose of this study was to construct and test a structural equation model of quality of work life for clinical nurses based on Peterson and Wilson's Culture-Work-Health model (CWHM). Methods: A structured questionnaire was completed by 523 clinical nurses to analyze the relationships between concepts of CWHM-organizational culture, social support, employee health, organizational health, and quality of work life. Among these conceptual variables of CWHM, employee health was measured by perceived health status, and organizational health was measured by presenteeism. SPSS21.0 and AMOS 21.0 programs were used to analyze the efficiency of the hypothesized model and calculate the direct and indirect effects of factors affecting quality of work life among clinical nurses. Results: The goodness-of-fit statistics of the final modified hypothetical model are as follows: ${\chi}^2=586.03$, ${\chi}^2/df=4.19$, GFI=.89, AGFI=.85, CFI=.91, TLI=.90, NFI=.89, and RMSEA=.08. The results revealed that organizational culture, social support, organizational health, and employee health accounted for 69% of clinical nurses' quality of work life. Conclusion: The major findings of this study indicate that it is essential to create a positive organizational culture and provide adequate organizational support to maintain a balance between the health of clinical nurses and the organization. Further repeated and expanded studies are needed to explore the multidimensional aspects of clinical nurses' quality of work life in Korea, including various factors, such as work environment, work stress, and burnout.

It is widely known that consumer satisfaction, as well as consumer voice and loyalty, affect firms' performance. Prior studies on consumer satisfaction have focused on expectancy disconfirmation theory and its effects on satisfaction related to disconfirmation with consumer expectation and with perceived performance. This study classified consumer expectation into should-expectation and will-expectation, and investigated how disconfirmation with these expectations affects consumer satisfaction differently based on regulatory focus. Specifically, for promotion-focused consumers, disconfirmation of will-expectation has a more significant influence on consumer satisfaction than that of should-expectation. For prevention-focused consumers, disconfirmation of should-expectation has a more significant influence on consumer satisfaction. The results of this study provide academic insights that not only generic expectation (will-expectation) but also should-expectation play an important role in determining consumer satisfaction according to regulatory focus. In addition, it is expected that the findings can be used as a guide to manage consumer expectation in practice.
